C#重用UDP端口号

IPAddress groupAddress = IPAddress.Parse( "239.0.84.11" );
Socket Listener = new Socket( AddressFamily.InterNetwork,SocketType.Dgram, ProtocolType.Udp );
Listener.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, 1 );
Listener.Bind( new IPEndPoint( IPAddress.Any, 8411 ) );
MulticastOption multicastOption = new MulticastOption( groupAddress );
Listener.SetSocketOption( SocketOptionLevel.IP,SocketOptionName.AddMembership,multicastOption );

希望对有这个需求的TX有所帮助 :)
